Every believer needs strength, without it you’ll faint. Troubles come your way to test your strength. It is not the size of your adversity that overwhelms you; it is your little strength that fails you.
Adversities are normal to destiny; it’s your strength that is mustered to control adversity. You must summon enough spiritual strength by the power of God.
If you must be strengthened you must wait upon the lord for it is those that wait upon the Lord that their strength will be renewed. Hence, anytime you wait on the lord you renew your power. Nobody waits on the lord in vain, whether or not the reason for the wait is met. God sure provides comfort and strength to those who trust in him.
